A novel BIB-based parallel download scheme

In the Internet, popular resources are located in multiple mirror servers that can serve the same information. To benefit from the situation and lessen the download duration, a novel parallel download scheme based on balanced incomplete block (BIB) design is proposed. The merits of the proposed scheme are not only to improve download time, but also to resist sufferings of a server fault or block loss caused by the network fluctuation. We implement our proposed scheme on a Perl's client, which support http 1.1. Through experiments, the proposed scheme is shown to be able to reduce the resources download time and improve the success download probability.
